Welcome to Android Central! Who gave you the phone? Did it belong to that person originally, or did that person also find the phone somewhere?

Android Device Manager is used to locate or lock a device remotely, if it's been lost or stolen. Is the phone showing something from Android Device Manager, or is it just asking you to enter the password?
